What is environmental testing? What is the main purpose of testing?


Environmental detection is atmospheric monitoring, which is the process of measuring the concentration of pollutants in the atmospheric environment, observing and analyzing their changes, and their impact on the environment. Atmospheric monitoring is the measurement of the types and concentrations of pollutants in the atmosphere, observing their spatiotemporal distribution and changes.
What are the main monitoring items for environmental testing?
Molecular pollutants: sulfur oxides, nitrogen oxides, carbon monoxide, ozone, halogenated hydrocarbons, hydrocarbons, etc. (monitoring of characteristic pollutants such as fluoride and lead can also be added according to different regional characteristics);
Granular pollutants: dust, inhalable particulate matter, total suspended particles, floating dust, and acid deposition.
Air quality monitoring is the sampling and analysis of the main pollutants in the atmosphere of a certain area. Regular monitoring of designated projects is usually carried out based on factors such as the scale of a region, the distribution and intensity of air pollution sources, meteorological conditions, terrain, and other factors.
Why do we need to do environmental testing?
(1) To provide a basis for studying the changes and development trends of atmospheric quality and conducting prediction and prediction of air pollution.
(2) By regularly or continuously monitoring the main pollutants in the atmospheric environment, it is determined whether the atmospheric quality meets the national atmospheric quality standards, and data is provided for the preparation of atmospheric environmental quality assessment reports.
(3) Provide basic data and basis for government departments to implement relevant environmental protection regulations, carry out environmental quality management, conduct environmental scientific research, and revise atmospheric environmental quality standards.
(4) Providing water quality testing, atmospheric testing and other projects for enterprises to develop monitoring plans, providing effective basis for maintaining nature and ecology.

How is witness sampling conducted?

Witness sampling is one of the supervisory management methods. Witness refers to the activity of on-site supervision by the supervising engineer on the completion of a certain process by the contracting unit. Witness sampling refers to the supervision activity of on-site sampling of materials, semi-finished products, and components related to structural safety used in engineering projects, as well as the inspection of the effectiveness of process activities.


What are the main testing items for building environment testing

Environmental testing mainly detects factors such as chemical pollutants and physical and biological pollution. Environmental detection and governance is a highly technical emerging industry that utilizes GIS technology to design environmental detection networks. The information collected from environmental detection can be stored and displayed in a timely manner through GIS, and detailed site monitoring and analysis can be conducted on the selected evaluation area.


How to detect the quality of construction projects?

Construction project quality inspection refers to the inspection of construction materials, building components, equipment, and physical quality of the construction site, as well as the testing of structural safety and main usage functions of the construction project design, in accordance with relevant national laws, regulations, and standards, commissioned by the inspection agency in the activities of building construction, expansion, renovation, and municipal infrastructure engineering.


What testing is required for building curtain walls?

Building curtain walls require physical performance testing (wind pressure resistance, air permeability, rainwater leakage, and plane deformation performance testing reports), which is generally referred to as the four properties testing of curtain walls, compatibility and adhesion testing reports of silicone structural adhesives and weather resistant sealants, and on-site tensile force testing reports of embedded parts.


What tests are required for curtain walls

Before installation, conduct a comprehensive inspection of the building and promptly rectify or rework any non-conforming areas.
